It is the first study to provide evidence that mindfulness yoga may offer effective treatment for depressed mothers-to-be.
Pregnancy hormones are known to cause mood swings, however one in five expectant mothers experience major depression.
Now, new research from the University of Michigan shows that the age-old recommended stress-buster could relieve their symptoms.
Mothers-to-be at high risk of mental health problems found significant relief from depressive symptoms after taking part in a 10-week programme. They also reported stronger attachment to their babies in the womb.
